Help! Can't place my lots

[halfbakedpeach]

Hello everyone this is my first post,
 I have all  the game packs except celebrations and have just gotten back into playing  after a long hiatus.

 I'm having two issues, first my scroll button doesn't work by holding it down to change the angle of my view and was wondering if there's another way to do it and next I can't place newly installed lots in my neighborhoods that have extra grids attached to them,it looks like the creator used the cheat to place things outside the grid which then in effect created the extra grid.....hope that makes sense...
   thank you in advance, Halfbakedpeach
